Ridiculously pathetic service and ************* goods sold

Last month I purchased a 6 pack Smirnoff guaranas. I was enjoying the pack until I had to take out a 3rd can out of the plastic wrap. As I touched this can, I could hear that something sounded funny, the can sounded hollow. When I tore the plastic wrapper more, I saw that the can was indeed empty. It was opened, there's no 2 ways about it. I sent msgs on Facebook- no reply, I called in and was assisted by Brandon, who advised me to send in pictures of the 6 pack. I did just that, only to get a reply saying that my complaint cannot be dealt with as SAB does not sell or deal with expired items and that I should take it up with the store.

I rep**** asking how I could be sent a response saying that my complaint cannot be dealt with. I had 2 ciders out of the pack. The slip I threw away as I bought it the week before I opened it. SO, my money goes down the drain??? I called in asking about the empty can , in the very tightly closed 6 pack. I don't even know where the expiry date is on the can. I even asked where is the expiry date because there is only a "MNF" date for Aug 2021. There is no BB, Best Before or Expires On, working anywhere. Only MNF which probably means Manufactured as I even enquired from my friends who work with goods like these when I told them about the faulty pack. SO, to date, no one rep**** on my follow up emails. I don't know if it is ***********s people working at the place, not knowing what MNF means, if it is just a place where, well...they don't care because hey, as long as they get the money for the goods, right? Pathetic service.
